The necklace costs $42.00 and another costs $28.00. The sales tax on the purchases is 8%. What is the total.

So neclace cost 42.00 and another cost 28.00 and tax is 8% or 0.08 so

we can add them together then tax them

42+28=70

then we add 8% of 70 to 70 so

8% of 70 is the same as 0.08 times 70=5.60

5.60+70.00=75.60

the total cost is $75.60
